Each day she eats 1/2 cups of rice. But we want to know how long it will take to each 2 cups worth. so lets make an equation.

.5x = 2
Divide both sides by .5

x = 4

So it will take 4 days to eat 2 cups of rice cereal.

Enter the next 3 terms from the geometric sequence below.

Katen [24]

Answer:

1/4, -1/8, and 1/16

Step-by-step explanation:

Geometric sequence: -2, 1, -1/2, ....

Geometric sequence means there is a common ratio.

so from -2 , the next term is -2*r , and the next term is -2*r*r

-2r = 1, means r = -1/2

then next after -1/2, is 1/4,

and then... -1/8, and then 1/16

Let A be a non-empty set of rational numbers and B = {a+1 : a ∈ A} (sometimes denotes A + 1). Prove carefully that sup(B) = sup(

liraira [26]

Answer:

a is an element of A; a is a rational number

(a+1) is element of B

Step-by-step explanation:

(a+1) = sup(A), which are the elements of B.

(a+1) + 1 = sup(B)

Recall a+1 = sup(A),

Therefore,

sup(A )+ 1 = sup(B)

sup(B) = sup(A) + 1 ___proved

Sup(A) means supremum of set A. It means least element of another set (say set B), that is greater than every element in set A

Ariana's password consists of 1 letter followed by 2 digits. What is the probability of correctly guessing Arabella's password?

AleksandrR [38]

Answer:

1/2600 = 0.00038

Step-by-step explanation:

To find this probability, we first need to find how many ways we can fill each letter and each digit.

The letter has 26 different values, and each digit has 10 different values, so to find the total number of passwords, we just need to multiply the possibilities for each letter and digit:

Total cases = 26 * 10 * 10 = 2600

So the probability of correctly guessing is 1/2600 = 0.00038
